I think i have an intake gasket leak at the back of my manifold........Intake to block on the rear of the car.... Anyhow, could someone please list all the possible reasons for having a backfire, so i can start going down the list... my car also feels down on power could this be why? Can an intake leak cause power loss? Would too much fuel pressure cause this as well, or too little fuel pressure

all this has came around since the edelbrock intake install... Not related, but i have a noisy valvetrain, i am thinking my pushrods are too short and not letting me achieve full lift while causing the noise. In light of that can someone explain to me how to cure this (pedestal mount roller rockers)


trying to answer multiple questions with one thread instead of the multiple ones i would have to start..

If the lower is leaking where it mates to the block you would also have a oil leak. Backfire with a loud pop is sometimes casue from a lean condition....hope this helps some.
